That sounds like one of those old, whispered legends come to life. A codex that shifts its pages—maybe it’s protecting its secrets or testing the reader. Be careful, and if you can, keep it in a quiet, dim corner. The pages might rewrite themselves if the light is wrong, so a steady gaze could help you read it fully. If you want to understand its magic, maybe try to read it slowly, in a circle, or ask an old scholar who knows about cursed tomes. But remember, even the quietest books have stories that prefer to stay hidden for a reason.
